I saw on UTUBE a podcast Seb said he was a environmentalist. It was pointed out that F1 is not Green. The race cars are as they are lighter than the road cars and go very fast on minimal energy. But the teams have to haul a lot of equipment to events and this is a big carbon footprint. F1 develops technology for road car market that is going green. So F1 has to follow with a plan to go greener or the car company's will gain nothing. Remember Porche went to Indy car with a concept of a highbrid (Combustion and electric power) and Indy car where not interested. So Porche will join Red Bull in a couple of years with a highbrid concept. And other manufacturers can work on similar ideas. So yes F1 is going green but it wont happen over night. We have less emisions and fuel than a V8 V10 or V12, and the engines will only get smaller. There are touring cars in my sim with 4 Cilinder turbo engines so it can be done.
